AIM: To know the more detailed findings of the small intestinal mucosa with the use of a magnifying endoscope and a vital dye, and the efficacy of the both tools. PATIENT AND METHODS: A 54-year old female patient with celiac disease. The duodenal mucosa downward as far as the descending portion was observed with a magnifying endoscope (Olympus GIF HM) before and after spraying the mucosa with 0.1% indigo carmine. RESULTS: The endoscopy clarified the atrophy and edema of each villus, and scattering of the dye revealed shorter villi with the relatively longer villi remaining in islands. CONCLUSION: The combination of magnifying endoscopy and the dye scattering method is useful for closer observation of the intestinal mucosa in celiac diseases.

Sodium butyrate (SB) provided orally favours body growth and maturation of the gastrointestinal tract (GIT) in milk-fed pigs. In weaned pigs, conflicting results have been obtained. Therefore, we hypothesised that the effects of SB (3 g/kg DM intake) depend on the period (before v. after weaning) of its oral administration. From the age of 5 d, thirty-two pigs, blocked in quadruplicates within litters, were assigned to one of four treatments: no SB (control), SB before (for 24 d), or after (for 11–12 d) weaning and SB before and after weaning (for 35–36 d). Growth performance, feed intake and various end-point indices of GIT anatomy and physiology were investigated at slaughter. The pigs supplemented with SB before weaning grew faster after weaning than the controls (P < 0·05). The feed intake was higher in pigs supplemented with SB before or after weaning (P < 0·05). SB provided before weaning improved post-weaning faecal digestibility (P < 0·05) while SB after weaning decreased ileal and faecal digestibilities (P < 0·05). Gastric digesta retention was higher when SB was provided before weaning (P < 0·05). Post-weaning administration of SB decreased the activity of three pancreatic enzymes and five intestinal enzymes (P < 0·05). IL-18 gene expression tended to be lower in the mid-jejunum in SB-supplemented pigs. The small-intestinal mucosa was thinner and jejunal villous height lower in all SB groups (P < 0·05). In conclusion, the pre-weaning SB supplementation was the most efficient to stimulate body growth and feed intake after weaning, by reducing gastric emptying and intestinal mucosa weight and by increasing feed digestibility.

The ingestion of wheat gliadin (alcohol-soluble proteins, an integral part of wheat gluten) and related proteins induce, in genetically predisposed individuals, celiac disease (CD), which is characterized by immune-mediated impairment of the small intestinal mucosa. The lifelong omission of gluten and related grain proteins, i.e., a gluten-free diet (GFD), is at present the only therapy for CD. Although a GFD usually reduces CD symptoms, it does not entirely restore the small intestinal mucosa to a fully healthy state. Recently, the participation of microbial components in pathogenetic mechanisms of celiac disease was suggested. The present review provides information on infectious diseases associated with CD and the putative role of infections in CD development. Moreover, the involvement of the microbiota as a factor contributing to pathological changes in the intestine is discussed. Attention is paid to the mechanisms by which microbes and their components affect mucosal immunity, including tolerance to food antigens. Modulation of microbiota composition and function and the potential beneficial effects of probiotics in celiac disease are discussed.

Integral membrane calcium-binding protein (IMCAL) is a vitamin D-dependent integral membrane protein that binds calcium with relatively high affinity (J. Biol. Chem. 225: 10834-10840, 1980). Specific immunoassays for IMCAL utilizing rabbit polyclonal and mouse monoclonal antibodies were developed and applied to studies of its tissue distribution and regulation by vitamin D3 and dietary calcium in the rat. The results indicate that vitamin D-dependent, cross-reactive protein is present in small intestinal mucosa, cecal mucosa, bone, kidney, brain, testis, heart, lung, spleen, and skin. Rats maintained on a low- (0.02%) compared with & high- (2.0%) calcium diet had significantly higher content of IMCAL in duodenal mucosa, cecal mucosa, bone, kidney, brain, testis, and heart. Treatment of rats on the high-calcium diet with 1,25-dihydroxyvitamin D3 increased the IMCAL content of the duodenal mucosa, cecal mucosa, and kidney. The widespread tissue distribution of vitamin D-dependent IMCAL, its close correlation in intestinal mucosa with the calcium transport mechanism, and its occurrence in isolated preparations of enterocyte plasma membranes (microvillus and basolateral membranes) suggest that the protein is involved in the regulation of calcium flux in a number of cell types.

Celiac disease (CD) is an immune-mediated enteropathy that develops in genetically susceptible individuals following exposure to dietary gluten. Severe changes at the intestinal mucosa observed in untreated CD patients are linked to changes in the level and in the pattern of expression of different genes. Fully differentiated epithelial cells express two isoforms of fatty acid binding proteins (FABPs): intestinal and liver, IFABP and LFABP, respectively. These proteins bind and transport long chain fatty acids and also have other important biological roles in signaling pathways, particularly those related to PPARγand inflammatory processes. Herein, we analyze the serum levels of IFABP and characterize the expression of both FABPs at protein and mRNA level in small intestinal mucosa in severe enteropathy and normal tissue. As a result, we observed higher levels of circulating IFABP in untreated CD patients compared with controls and patients on gluten-free diet. In duodenal mucosa a differential FABPs expression pattern was observed with a reduction in mRNA levels compared to controls explained by the epithelium loss in severe enteropathy. In conclusion, we report changes in FABPs’ expression pattern in severe enteropathy. Consequently, there might be alterations in lipid metabolism and the inflammatory process in the small intestinal mucosa.

Vitro Model

Two patients with cystic fibrosis (CF) who subsequently developed celiac disease (CD) are described. Since organ culture of intestinal mucosa has been used to establish an in vitro model for the study of CD, we utilized this opportunity to determine whether duodenal mucosa obtained from each of these two patients and their immediate families differed in its organ culture behavior from mucosa obtained from patients with CD alone. Additionally, as specific HL-A types are associated with CD, we used HL-A typing to determine whether the two patients with CF-CD differed genetically from patients with CD alone. One of our patients was HL-A8, the most common type associated with CD; the other was HL-A12, as are many of the non-HL-A8 celiac patients. The response in organ culture of the mucosa of these two patients was the same as the response in organ culture of the mucosa from patients with CD alone. These and other data suggest that CD occurring in patients with CF is no different than CD occurring alone.

<i>Strongyloides stercoralis</i> is an intestinal nematode that colonizes and reproduces in the upper small intestinal mucosa. Infection in immunocompetent hosts is self-limited but in immunocompromised patients it can be complicated and cause hyperinfection. We present a 60-year-old female who was admitted due to an exacerbation of acquired thrombotic thrombocytopenic purpura requiring high doses of corticosteroids. The patient began to experience persistent pyrosis, nausea, vomiting, and oral intolerance. She was di­agnosed with syndrome of inappropriate secretion of antidiuretic hormone (SIADH). Upper endoscopy was performed and showed esophageal, gastric, and duodenal mucosa with edema and erythema. Moreover, there were superficial erosions and thickened folds in duodenum. Gastric and duodenal biopsies were taken. Abdominal computed tomography and magnetic enteroresonance displayed duodenal dilation and inflammatory changes. The histological study of biopsies showed colonization by <i>S. stercolaris</i> in the antrum and duodenum. <i>S. stercolaris</i> is a human parasite that is endemic in tropical, subtropical, and temperate regions. Its lifecycle is complex because it completes its entire cycle within the human host; it penetrates the skin, migrates to the lungs, and reach the gastrointestinal tract. The most affected site is the duodenum and upper jejunum. The lifecycle includes autoinfection through the intestinal mucosa or perianal skin, especially in immunocompromised hosts. Immunossuppression can lead to hyperinfection syndrome and disseminated disease. However, involvement of the stomach has relatively rarely been reported. SIADH has been related to systemic hyperinfection, although the mechanism is not clear. The relatively nonspecific clinical and imaging features and the low sensitivity of routine parasite tests make the diagnosis challenging and delayed.
